United States vPatent O M' l This invention relates generally to atomizers, but more particularly to the construction of the nozzle end thereof, and is an improvement and continuation in part of application Serial Number 62,207 filed by the same applicant herein in the United States Patent Office on November 26, 1948, now Patent No. 2,578,907.

The main object of the invention herein is to provide a nozzle for a `resilient container or`bottle adapted to receive a uid and to effect atomizing action thereof, the said nozzle being provided with a depending socket formation for resilient connection with an internal conductor tube of the container and through which the fluid content is forced toward the nozzle end.

A further object of the present invention is to provide an atomizer wherein thewalls of the container are resilient and operable to effect atomizing action and wherein the nozzle end is in the form of a closure made of puncturable plastic or like material and having a depending or internal effective socket formation which is suiciently yieldableto give with slight displacements of an internal tube slidably engageable therewith.

A further object of the invention is to provide an atomizer wherein the nozzle end is of simple construction, inexpensive, adapted to be sealed for shipment, easy to place into operation, durable, compact and efiicient in operation;

These objects and other incidental ends and advantages of the invention will hereinafter appear in the progress of the disclosure and as pointed out in the appended claims. .Accompanying this specification are drawings showing preferred embodiments of the invention wherein: p p

Referring now to the figures, 20 represents a container such as a bottle shape, having a neck portion 21 and formed of resilient flexible material such that after being depressed the container will take on its original shape onthe release of the fingers; One material which has been found to be suitable for this purpose is polyethylene. Other similar plastic materials or rubber material is suitable.

The neck portion 21 is formed internally with a long seat 22 and a shoulder 23 for receiving and retaining a nozzle 24 having a complementary seat 22a and shoulder 23a. The shoulder 23 prevents the easy withdrawal of the nozzle and the extension of the nozzle from theneck of the container as the container is operated to place pressure behind the nozzle.

As shown in Figures 2-8, nozzle 24 has a central socket formation adapted to frictionally engage a conductor tube 2S which depends into the fluid contents of container 2 0 to a location near the bottom of the same s'o that uid will be transferred from the bottom and projected upwardly. The effective socket or sleeve of the nozzle is formed from a plurality of spaced ribs vertically and radially disposed and extending from the inner Vandv under sides of the side and top walls of the nozzle 24, the said ribs each being indicated by numerals 26, 26a, 27 and 27a. The inner vertical walls of said rib members fonn the socket in which tube 25 is adapted to be frictionally engaged, there being provided on the inner longitudinal walls of ribs A26 and 26a shoulders 26b and 26e to serve as an abutment for the tube 25. The passages between adjacent rib members communicate with a reduced orifice 28 in the top Wall of nozzle 24, said orifice being in line of communication with the upper end of tube 25. Each of the passages between the rib portions as indicated by numeral 29 permits upward flow of air from the container as it v is'being operated and at the same time permits down- Ward flow of air to maintain an air pressure over the top of the contents of the container.. These passages are straight and not curved or bent eliminating possibillity of trapping of fluid contents which evaporate subsequently and serve as obstructions to air passage.

N ozzle 24 is made of any plastic material which is capable of being cutas by a knife and is provided with a closing tip 30 over orifice 28. The tip must be severed in order that the liquid can be dispensed through orifice 28 in communication with passages 29 between the inner vertical walls of the ribs 26, 26a, 27 and 27a. The tip 30 is shown in place in Figure 1, but may be removed as shown in Figure 2 in order to permit atomizing action.

The top wall 31 of nozzle 24 is depressed about a peripheral wall 32 for retaining any liquid or uid after the tip 30 is cut down ush; such liquid as received by the upper end of the nozzle will drain back into the container.

It is seen that the conductor tube 25 as applied to the socket formed between the rib members of the nozzle is capable of iiexing to the same degree as the socket member formed from the ribs. Such exible connection is adapted to prevent the breaking off of conductor tube 25 when the container Walls during squeezing for atomizing action contacts said tube or whenever the tube is displaced for any reason.

On the exterior neck portion 21 is a circular flange 33 and a single turn thread 34. When the container has once been opened and is not in use, a cap 35 having a cooperating internal groove 36 may be seated upon the thread ange 34 and retained thereby. Thus there has been provided an atomizer wherein the container itself is used for effecting the atomizing action and where the nozzle in the neck portion is sealed as by tip 30 for shipping purposes. By a simple operation of removing tip 30, the container can be adapted for use. By a simple squeeze of the container itself a spray of the contents is extended through orice 28 of the nozzle. The nozzle is so designed that it is positively retained in the neck portion and will not be readily released therefrom as the result of pressure being brought upon the interior of the neck portion and upon the under face of the nozzle.

A second embodiment of the nozzle portion of the atomizer is shown in Figures 9, 10, 11, 12 and 13. The socket for the tube in this second embodiment is formed by means of a plurality of depending rods of any material such as plastic indicated by numerals 37, 38, 39 and 40. These rods depend and are secured to the under portion of the top wall 31 of the nozzle and some or all of said rods are provided with shoulders such as 41 and 42 to serve as an abutment for the conductor tube 25. The inner longitudinal edges of rods 37-40 serve as a socket for the tube While the spacing therebetween provide passages such as 43 and 44 communicating without bends to orifice 28 to etect atomizing action of the liuid carried up through conductor tube 25.

A third embodiment of a nozzle is shown in Figures 14, 15, and 16 wherein a depending central sleeve 45 is provided which communicates with the reduced orice 28, the said sleeve having a plurality of obliquely positioned passages each designated by numeral 46 and penetrating the side Walls of the sleeve 45 and communicating without bends with orifice 28 whereby air upon the squeezing of the container is forced through the oriiice 28 to cause atomization of the fluid through the conductor tube 25.

The sleeve 45 is provided with an internal shoulder 48 to provide an abutment for tube 25. It is to be emphasized that in all the embodiments of the invention the air passages are virtually in direct and straight communication with the orifice 28 to prevent possibility of bends which would bring about clogging and ineiiiciency.

In a fourth embodiment of a nozzle as shown in Figures 17 and 18 is a socket for conductor tube 25 which is secured to nozzle 24 by means of a ring member 49 supporting a central subordinate sleeve 50 by means of webbing 51. The sleeve 50l is provided with an internal shoulder 52 to act as an abutment for tube 25 and empties into orifice 28 with spacing therearound as indicated by numeral 53. Air is forced through the webbing 51 and through the spacing 53 to atomize uid proceeding from tube 25. The ring member 49 is secured to the inner side walls of main nozzle 24 by means of an inclined seat 54 and a shoulder 55 engaging a corresponding seat and shoulder in nozzle 24.

It is thus seen that the nozzle of the invention herein permits a exible connection with a conductor tube to prevent the latter from breakage or displacement and further has air passages which are substantially straight and in communication with the orice 28 so that no bends or circuitous paths are provided for the passage of air. It is understood however that orifice 28 need not be coaxial with tube 25 although it is so as shown.

I wish it understood that minor changes and variations in the material, construction, shape and integration of parts may all be resorted to Without departing from the spirit of the invention and the scope of the appended claims.
